similar artists, lyrics and videos widgets work fine
issue exists for other user

running amarok-2.3.1-3.5.x86_64 and this has been an issue for a while


konqueror sends an id string (forum thread)
there's nothing in ~/.xsessions when amarok started with --debug, suggestion made in thread to look for http errors

running with debug shows (though not all together):
amarok: wiki url: "http://en.wikipedia.org/w/index.php?title=Allen%20Toussaint%20%28band%29&useskin=monobook"
amarok: BEGIN: void WikipediaEngine::update()
amarok: BEGIN: bool EngineController::isStream()
amarok: END__: bool EngineController::isStream() - Took 3.2e-05s
amarok: wiki url: "http://en.wikipedia.org/w/index.php?title=Allen%20Toussaint%20%28band%29&useskin=monobook"
amarok: END__: void WikipediaEngine::update() - Took 0.0033s
amarok: BEGIN: void WikipediaEngine::wikiResult(KJob*)
amarok: END__: void WikipediaEngine::wikiResult(KJob*) - Took 0.00016s

Try running "kdebugdialog" and enabled the "kio_http" area, then testing again. The output should be into ~/.xsession-errors.

nothing appears in ~/.xsession-errors (tested both with and without debug option in Amarok)

but there is this message from when when in konsole:
QWidget::setMinimumSize: (/QWidget) Negative sizes (224,-15) are not possible

Can you please try logging out and logging back in? There should be at least some messages from "kio_http" present there since Amarok uses KIO...

I ran kdedebugdialog and didn't see anything obvious in the log

BUT I did find one album/artist that actually worked for me (Modest Mouse), but still none of the others attempted did

this is what I think might be the relevant xsessions-errors for 2 diff artists:

It appears that it worked when it had the page cached, but not when retrieving it live... interesting.

The instance displayed showing the retrieval from cache might not have been the first in the ~/xsession-errors file that day as I had been trying different artists and that one multiple times. FYI when playing that artist as a different user for the first time it (Modest Mouse) played properly in the wiki wwidget.

Where's the cache it retrieved if from, so I can test with it cleaned? I deleted all the usual /var/tmp and /tmp and tmp-xxxx and cache-xxx and Amarok still finds the Wiki for that artist

The cache is stored in /var/tmp/kdecache-$USER/http I believe. You may have to log out and back in for it to have any effect however.

I logged out and cleaned all the caches (~/.kde. /tmp, /var/tmp) and get the same result, only thing showing in wiki is Modest Mouse

Oddly enough I'm having the same issue with the Wikipedia applet, although besides Modest Mouse, I also get some other bands to pop right up - quite a variety: Death Cab for Cutie, R.E.M., Frou Frou, Radiohead, Presidents of the United States of America, Fastball, Ash, Espers, No Doubt (listening on random, to test this). The rest just look as they are loading, forever. This behavior is the same using both the vlc and xine-phonon backends. Amarok Version 2.3-GIT, using KDE 4.4.85 (KDE 4.5 Beta2)).

Valorie

@valoriez - Weird I have a Death Cab For Cutie and wiki doesn't show for it (note "For" has capital "F" in my collection). Don't have any of the others that work for you.

posted bug https://bugs.kde.org/show_bug.cgi?id=243617

update - as of an update I installed today wiki widget now works

amarok-2.3.1.60svn20100625-37.7.x86_64

Interesting. I just built today, and nothing has changed. Some artists show, while the majority do not.

Same problem with lyrics, too. Sometimes they work (or reappear?), and sometimes just endlessly "load."

Even stranger, I don't see any problems with Wikipedia at all other than those were no Wikipedia page is available (nothing we can do about), just lyrics are not always found, but that can well be a lack of popularity of some tracks I listen to. Using current Amarok 2.3.1-git.

So I wonder if this could be an individual network setting that is to blame?
